Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542494, here are decompositions:

5 + 542489 = 542494
11 + 542483 = 542494
47 + 542447 = 542494
53 + 542441 = 542494
233 + 542261 = 542494
257 + 542237 = 542494
311 + 542183 = 542494
353 + 542141 = 542494

Showing the first eight; more decompositions exist.
